Similar referencecharacters'refer to similar IIL. preferably of'flexible rubber, may be ex-v` The form of the invention shown in Figs.3 and 4 is made and assembled in substantially the same Way as abovedescribed in connection with Figs. 1 and 2, the similar parts beingdesignated by prime reference numerals. In this form the innerperipheraledge of the supportingsheet metal panel i9 is bent to provide an angularflange I8. This flange I8 is turned at such an angle as to provide asmooth surface over which the enlargement 26 on wedging strip 25 is moreeasily forced during insertion of said wedging strip. Also in this formof Figs. 3 and 4, the surface 2l' of main body strip I0 has an abruptshoulder 28 which interlocks with a corresponding shoulder on wedgingstrip 25' to retain saidwedging strip in assembled position.

The form of the invention shown inFigs. 5-

and 6 is similar in many respects to the forms hereinabove described.The wedging strip 'ed and main body strip li! are integrally connectedby a; relatively thin and flexible continuousv hinge portion 42. Thisintegral strip may be extruded thru an extrusion die with the wedgingstrip 40 suitably separated from main body il except at the connectinghinge portion d2, for. example inthe position shown in Fig. 6, and curedinthat position so that Fig. 6 represents the normal or unstressed shapeof the cured strip. However the hinge portion 42 is sufficientlyfiexible to permit the wedging strip 40 to be readily swung clockwise(as viewed in Fig. 6) thru approximately 180 degrees (if necessary) forassembling purposes.

In assembling this strip upon the connected panels the mounting strip isapplied around the edges of the window opening in metal panel Sii byfirst inserting said edges edgewise snugly into grooves 5|. Then theglass pane B is moved into position at the window opening and thewedging strip portions 40 are swung outwardly about the hinges 42sufficiently to permit the glass pane 6) to pass laterally thereover andinto contact with the surface 6I, that is, approximately into theposition shown in Fig. 5. Thereafter the wedging strip portions El! areswung counterclock- Wise .into contact with the glass pane 50 and forcedinto final position shown in Fig. 5 by squeezing the enlargement thereonthru the suitably narrower neck opening defined by the inner edge 66 ofthe glass pane 60 and the shoulder 41 on main body 4|. Afterwedgingportion Ml is forced to its final position itis retained in placeby its shoulder 48 locking under the inner edge of glass pane 60. Theglass engaging suryface 49 of wedging portion 4i) is pressed tightlyagainst glass pane cil and thus seals both sides of said pane. Thereaction of wedging portion @all on main body 4l compresses the adjacentdeformable material thereof and hence causes wingL faces i3 and 44 inFig. 6) may be inclined up, wardly at say from 30 to 45 degrees and yetper' mit the lateral passage of pane 60 into position as abovedescribed.

rlhe forml of the invention shown in Fig. 7 is similar to that of Fig. 5and is made and assembled upon the connected parts in a similar manner.lThe similar parts are designatedfby Lns '4 prime reference numerals. Inthis form the supporting metal panel has a laterally extending flange'I0 against which the wing portion 39 is directly compressed when thewedging portion 4U is Iforced into its nal position shown in Fig. 7.Thus the angular upwardly extending wing 1I is more firmly backed up byflange 10 when the wedging portion 40' is squeezed into its finalposition. The inclination of the surface 44' on wedging portion 40 andits complementary surface 43 on main body 4l against which it presses issuch that wedging portion 40 will be retainedn final position by thepressure engagement between said surfaces 43' and 44'. Lateral forceagainst glass pane 60 to the right (as viewed in'Fig.l 7) will increasethe pressure of surface l-lli on'surface 43' and in View of theinclination of these surfaces will obviously have no tendency to swingwedging strip 40' clockwise out of its nal position. This lateral forceagainst glass pane-lill' isV resisted by the wing portion Il; which.isyinturn firmly backed up by flange lllasjstatedffabove. In this formof the invention the resilient-I deformable material of the mountingstrip Amay be materially harder and hence strongerthan is customary withmounting strips used for similar purposes since less distortion thereofis required in order to assemble the strip upon the .two joined panels.

Allforms of the invention are shown in the drawings on an enlarged scalebeyond such strip sections ordinarily used in mounting glass panes inautomotive vehicles or the like. In the forms formed of resilientdeformable material for joinf ing adjacent margins of two panels,comprising:
